Positional parameters cannot be used after named parameters |yiyi2

Question

I am taking the Yii2 PHP framework course and I encountered a problem. I'm not very familiar with PHP so I'm having a hard time figuring this out.

So I tried to create a "Delete" button in my website but I got the error: "Cannot use positional parameters after named parameters".

There are code snippets:

'class' => 'yii\grid\ActionColumn',
'buttons' => [
    'delete' => function ($url) {
        return Html::a(text:'Delete', $url, [
            'data-method' => 'post'
        ]);
    }
]
